Only lucrative to those whales who happens to hold a sizeable sum of eth, that can not be compared to an individual who for instance can only afford to buy 1 eth probably at the cost of $500 and now that the price of eth has pump up to $1000, waw! $500 profit... not bad,
what about those who bought above that price! how lucrative is that, most good project can be consider lucrative depending on the time you get in and the amount you hold.
